I don't know if this will help anyone. But the therapist I am seeing deals mainly with anxiety and phobias. He's been in the field for nearly 40 years. He has a blog and coaches an online support group (I haven't checked that out yet), but I do find the blog a very interesting read. It isn't necessarily about emetophobia, but I do see how they all sort of relate. I do usually end up taking something away from each post I read. Actually, the most recent one has a little paragraph about me specifically (the emetophobia story), but it's very general and probably relates to all of us.
His blog is called ruled by fear (at ruledbyfear.com), so it should come up if you search for that. I wasn't sure if I could post a link, since I just read in the previous post about a blog, and they weren't allowed to post a direct link on this site.
